超宽桥面斜拉桥前支点挂篮设计

Design of Front Support Point Construction Cradle of the Cable-stayed Bridge with Extra-wide Beam

针对桥面宽度37.6m的某高速公路斜拉桥,设计了一套超宽、适用的前支点挂篮,运用大型通用有限元软件对挂篮施工进行了模拟计算,对挂篮各部位进行了安全验算分析,经分析,挂篮各部位满足各个施工工序的受力要求,有效指导了施工。

A set of wide and available front support point construction cradle is designed according to the highway cable - stayed bridge with 37. 6m extra - wide beam, the simulation calculation of construction are conducted by used the large - scale common finite element software, The structural security analysis of the different parts of the cradle was carried out. Through analysis, the different parts of the cradle meet the stress requirements of each construction process, and effectively guide the construction.
